Jlieii tlie clip is implied to :i pziir of reinforcing liars l5 und i6 the :iriiis of loop 2 pass 'from tlie legs find (3 around tlie under side of bnr lo over tlie iipper liiii l5. The curved enrol lZ of erin 7 grips the upper side of bar l5 :it iilioiit tlie locution et one side oi' imi' lo tlizit loop 2 is :it tlie other side. The eiiried end l-l of the ziini 8 engages the under side of lizii 15 it zi point beyond the loop The clip being made of resilient iiinterinl, the locking arm 8 is normally urged to return to the position indicated by dotted lines. lint :is this movement is prevented by tlie reinforcing liiii l5 the notion will cruise the clip to irnily engage tlie bar 1G :it points 1L and to engage the bnr 15 at tlieoiirve in loop 2, and tlie end ol arm 7. T lie oars are by this niesiiis firmly tied together.

'in applying tlie llip to the intersection of zi, pair of reinforcing liars, referring to Fig. 2, its ends 12 sind lil passed dofi'nwzirdly iit eiieli side of mir 15 the right of bar i6 and tlien caused to pass upwardly :it each eide of bur l5 to the left ot Toer 16, coming to-tlie position indicated in 1 with arm l0 extending iipiiiiidly :i indicated lof; tliedotted. lines. lin position the clip is fiirljf loose sind free to .inove on tlie reinoriiig liars, lout by springing the iirin l0 :ironnd tlie liar l5 so tliiit its .Curved end lli engages the iiiidei" side oic the bei', the clipV beeoiiies tightly engaged with botli of' tlie lie seine togetliem The end oi erin 7 may belettzis iiidieiigtegl by the dotted lines in Fig; l, or curved iis sliowii li); tl'ie full lines.
